port speed, and data is not being sent or received.

Link indicator is blinking green, and activity is off. NIC identify is enabled through the NIC configuration utility.

Power supply unit indicator codes

AC power supply units (PSUs) have an illuminated translucent handle that serves as an indicator. The indicator shows whether

power is present or if a power fault has occurred.

Dell EMC PowerEdge T440 system overview

Figure 11. AC PSU status indicator

1. AC PSU status indicator/handle

Table 10. AC PSU status indicator codes

Power indicator codes Condition

Green A valid power source is connected to the PSU, and the PSU is operational.

Blinking amber Indicates a problem with the PSU.

Not illuminated Power is not connected to the PSU.

Blinking green When the firmware of the PSU is being updated, the PSU handle blinks green.

CAUTION: Do not disconnect the power cord, or unplug the PSU when updating

firmware. If firmware update is interrupted, the PSUs do not function.

Blinking green and turns

off

When hot-plugging a PSU, the PSU handle blinks green five times at a rate of 4 Hz and powers off.

It indicates a PSU mismatch regarding efficiency, feature set, health status, or supported voltage.

CAUTION: If two PSUs are installed, both the PSUs must have the same type of label;

for example, Extended Power Performance (EPP) label. Mixing PSUs from previous

generations of PowerEdge servers is not supported, even if the PSUs have the same

power rating. It results in a PSU mismatch condition or failure to power on the

system.

CAUTION: When correcting a PSU mismatch, replace only the PSU with the blinking

indicator. Swapping the PSU to make a matched pair can result in an error condition

and unexpected system shutdown. To change from a high output configuration to a

low output configuration or conversely, you must turn off the system.

CAUTION: AC PSUs support both 240 V and 120 V input voltages except for Titanium

PSUs, which support only 240 V. When two identical PSUs receive different input

voltages, they can output different wattages, and trigger a mismatch.

CAUTION: If two PSUs are used, they must be of the same type and have the same

maximum output power.

Locating the Service Tag of your system

You can identify your system using the unique Express Service Code and Service Tag. Pull out the information tag in front of the

system to view the Express Service Code and Service Tag. Alternatively, the information may be on a sticker on the chassis of

the system. The mini Enterprise Service Tag (EST) is found on the back of the system. This information is used by Dell to route

support calls to the appropriate personnel.
